BRODERICK HASKELL, OF GRAND RAPIDS, MICHIGAN.

SPECIFICATION forming part of .Letters Patent No. 610,603, datedSeptember 13, 1898.

Application filed March 11, 1898.

To all whom, t may concern:

Be it known that I, BRODERICK HASKELL, a citizen of the United States,residing at Grand Rapids, in the county of Kent and State of Michigan,have invented certain new and usefulmprovements inCarpet-Sweepers; and Ido hereby declare the following to be -a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to improvements in carpet-sweepers; and its objectis to provide the same with meansfor preventing the escape of fine dustfrom beneath the case and collecting the same; and it consists,essentially, in combining with a carpet-sweeper a blower to create aninward draft of air between the case and carpet and to discharge thesame through a passage in which is a dust-collector, as hereinafter morefully described, and particularly pointed out in the claims, referencebeing had to the accompanying drawings, in which- Figure l isatransverse vertical section of .a device embodying my invention, takenon the line l l of Figs. 2 and 3; Fig. 2, a longitudinal verticalsection of the same on the line 2 2 of Fig. l; and Fig. 3, a plan viewof the same, with parts broken away to'show the construction.

Like letters refer to like parts in all of the figures.

A represents the case, of substantially the usual form, having therotary brush E and means for rotating the same and provided with anopening A in one of its inclined sides for egress'of air from the blowerand a door A through which to insert and remove the sponge G, whichsponge is located in an airpassage B,- extending inward from the openingA to the blower-casing B. Said passage and casing are preferablyformed'by a continuous strip of sheet metal extending hori- `zontallyfrom the lower side of the opening A to about the middle of the case,and thence in a curve around the axis of the shaft carrying the fanterminating in an incomplete cylinder, leaving an opening for escape ofair at the side toward the opening A. The end walls of this casing andpassage are formed Serial No. 673,443. (No model.)

by flat plates, and the top of the passage from vthe casing of the fanto the opening A is in the end walls of the case A and provided with adriving-pulley H on its outer end', engaging the drive-wheel D of thesweeper to rotate the fan and induce an inward current of air between.the case and the carpet and an' outward current of air from said fanthrough the passage B. i

In operation the sponge Gis moistened with Water, and the current of airinward beneath the case and outward throughsaid sponge prevents thelight dust from escaping from beneath the case and carries it into thesponge, where it is retained and from which it is easily removed bywashing the sponge in water.

Having thus fully described my invention, what I claim, and wish tosecure by Letters Patent, is

l. The combination of a carpetsweeper case having an opening for egressof air, a shaft having a pulley to engage a drive-wheel of the sweeper afan on said shaft, a'casing and air-passage formed by a continuous striplof sheet metal extending horizontally from the lower side of saidopening to near the middle of the case, and thence in a curve about theaxis of said shaft, and end plates having openings around said shaft,and a sponge in said passage, substantially as dea scribed.

2. In a carpetsweeper, a case having an egress-opening and a door in itstop, an airpassage below said door, screensat each end Vof saidair-passage, a sponge in said passage,

a fan-casing at the inner end of said passage having axial openings, ashaft in the axis of said casing having a pulley engaging thedrive-wheel of the sweeper, and a fan on said shaft, substantially asdescribed.

' 3. In a carpet-sweeper the combination of a case having an opening inoneof its inclined sides, and a door in its top adjacent to saidopening, a shaft journaled in said case, afan ease and a sponge in theair-passage and bexo tween said screens substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.'
